 golang web项目脚手架,对常用组件进行封装,通过配置文件初始化后即可方便使用,避免每次创建新项目都需要初始化各种组件的业务逻辑
+
 ## 包含组件
- -  `viper` github.com/spf13/viper 配置
- -  `xorm` xorm.io/xorm mysql orm
- -  `gin` github.com/gin-gonic/gin web框架
- -  `pprof` net/http/pprof gin debug 模式默认打开pprof
- -  `zap` go.uber.org/zap 日志处理
- -  `context` 简单封装
- -  `redis` github.com/go-redis/redis/v8
- -  `util` 常用函数
- -  `httpclient` http 请求简单封装

 ### 如何找到配置文件
- 1. go run main.go -c config.toml 使用 -c 加本地配置文件路径
- 2. export CONFIG_PATH=./config.toml 使用环境变量指定本地配置文件
- 3. 不使用本地配置文件环境变量直接指向配置中心

 配置文件中的 redis 和mysql 可以设置多个使用的时候只需要选择对应的配置即可
